Hang on, this looks like IOL are blocking Eircom (based on pretty
dubious information).

That is, 193.120.142.80 (hub01.mail.iol.ie) is refusing to deliver mail
received from 159.134.118.23 (mail07.svc.cra.dublin.eircom.net) because
of a Spamcop report about it. Eircom are guilty of the following
terrible crimes:

* Been reported as a source of spam less than 10 times
* Been detected sending mail to spam traps
* Been witnessed sending mail about 5290 times

Knowing that this server belongs to a widely-used ISP (with it's fair
share of virus-riddled and otherwise clueless users), none of these
things is particularly surprising.
